Conversion uses exact internationally defined unit factors where available.
How to use Length Converter
Convert lengths between the supported metric and imperial units without manually looking up each conversion factor.
- Enter the numerical length.
- Choose the unit the value is currently expressed in and the destination unit.
- Convert and read the result with its destination unit.
Worked example
1 inch equals 2.54 centimetres; 1 foot equals 0.3048 metres. These conversion factors are exact, while displayed calculations can be rounded.
Limits and things to check
This is a length converter, not an area or volume converter. Use squared or cubed conversion factors for those quantities instead.
Can I enter feet and inches together?
Use a single numerical value in the selected unit. For example, 5 feet 6 inches is 5.5 feet or 66 inches.
